This invention aims to provide a novel means whereby the sashes of a window may be held against a parting strip, thereby to ide the sash as it moves up and down, and

- to hold the sash against the parting strip tightly, thereby to keep out the weather.

' It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the inven- 10 tion appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in elevation, a device constructed in accordance with the invention;

, Figure 2 is a longitudinal section;

Figure 3 is a fragmental transverse section. The numeral 1 designates a window frame including stiles 2 and a lintel a Guide strips 4 are secured to the stiles 2 and to the lintel 3. Guide strips 5 are secured to the stiles 2 and the lintel 3. Between the guide strips 1 and 5 are located parting strips 6 which are secured to the stiles 2. Above the I parting strips 6 are located channel-shaped and the parting strips 6 and 7' form guide ways 10. The guide strips 5 and the parting strips 6 and 7'form guide ways 11. An

upper sash 12 slides in the guide way 11,

and the lower sash 14 slides in the guide way 10. Wear strips 15 are provided and are reversely bent to form flanges 16 that slide in contact with the inner surfaces of the channel-shaped parting strips 7. The wear strips 15 are made of some metal that will slide upon the metal parting strips 7 with but little friction. The flanges 16 form a reinforcement and practically vdouble the life of the wear strips 15, since after the flanges 16 have been worn away, the outer ends of the wear strips 15 still can be pressed against the inner surfaces of the parting strips 7 by a means now to be described.

The spring tongues 17 are overlaid on the wear strips 15. Securing devices 18, such as screws, pass through the outer ends of the spring tongues 17 and through the outer ends of the wear strips 15, the spring tongues 17 and the wear strips 15 thus being held on the sashes 12 and 14, transversely of the stiles of the sashes, as shown in Figures 1 and 3. Adjusting members, such as screws 19,.ex-

-- tend through the spring tongues 17 and through the wear strips 15, the adjusting members 19 entering the sashes 12 and 14.

The spring tongues 17 are curved as shown at 20 so that their ends bear upon the wear strips 15, the intermediate portions of the spring tongues 17 being spaced from the wear strips 15 for the sake of adjustment, it being possible to move tl1e screws 19 inwardly, thereby to adjust the pressure which the spring tongues 17 exert on the wear strips 15, and, thereby, to adjust the pressure with which the wear strips 15 bear upon the channel-shaped parting strips 7.

The spring tongues 17 hold the sashes 12 and 11 tightly against the parting strips 7, and the weather is prevented from finding its way in. The device, moreover, prevents the sashes 12 and 14 from rattling, and a smooth working window structure is provided.

Having thusdescribed the invention, what is claimed is 1. In a device of the class described, a window frame, a parting strip on the frame, a sash slidable \along the parting strip, a spring tongue, a wear strip interposed be-. tween one end of the tongue and the parting strip, and a securing element connecting the opposite end of the tongue and the wear strip to the sash.

2. Ina device of the class described, a. window frame, a parting strip on the frame, a sash slidable along the parting strip, a spring tongue, a wear strip interposed be- 5 tween one end of the tongue and the parting strip, and securing elements connecting the opposite end of the tongue and the wear strip with the sash, one of the securing ele- 1 ments being adjustable in and out to vary the pressure wherewith the tongue bears on the wear strip.

3. In a device of the class described, a window frame, a parting strip on the frame, a sash slidable along the parting strip, a spring tongue, a wear strip interposed between one end of the tongue and the parting strip and reversely bent upon itself to afford an extra layer between the tongue and the parting strip, and inner and "outer securing elements connecting the opposite end of the tongue and the wear strip with the sash, the inner securing element being adjustable with respect to the sash to vary the pressure of the tongue on the wear strip. In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.
